T 0 all whom it may concern:

Be it known that we, ALBERT GALLATIN DAVIS and MAX FLANDERS, citizens ofthe United States of America, residing in the city of Pueblo, in thecounty of Pueblo and State of Colorado, have invented a certain new anduseful Improvement in Nut-Locks, of which the following is aspecification.

Our invention relates to improvements in nut locks, and our object is toproduce an inexpensive, simple and positive lock for general utilityWherever bolts and nuts are used and safety of fastenings desired, andwhich may be used with the ordinary form of nut. Ve attain these objectsby the de vice illustrated in the accompanying drawings in which Figure1 is a side view of a bolt with a groove A therein Fig. 2 is aperspective view of the locking device with the nut locking finger C inits original form prior to using; Fig. 3 is a similar View of thelocking device with the nut locking finger C bent to lock the nut; Fig.4 is a similar View of the nut to be applied to the bolt, and Fig. 5 isa similar View showing the nut on the bolt and the nutlocking deviceapplied thereto, so as to positively lock the nut upon the bolt.

The locking device may consist of a piece of wire or of soft steel orany malleable or flexible metal or other suitable substance, preferablysquare in cross-section, the body of which is bent or curved as shown inthe drawings, with a short spur or lug bent inwardly in the plane ofsaid body to fit the groove A of the bolt as shown in Fig. 5, and

the ring portion thereof may be made of such diameter that it fits thebolt to which it is to be applied. The bolt must have the groove A inorder to admit the spur or lug of the nut locking device.

In applying the invention to its intended purpose, the device of Fig. 2is appropriately engaged upon the bolt, the inwardly extending lugthereof occupying the groove A of the bolt, Fig. 1; the nut is thenapplied to its desired position upon the bolt and the nut locking deviceis then fastened by bending the finger C over upon the nut so as tooverlie one of the faces thereof as shown in Fig. 5.

Having thus described our invention, what we claim is:

The combination of a threaded bolt having a longitudinal groove, athreaded nut engaging the same, a locking device consisting of a narrowcurved strip of malleable material substantially surrounding the bolt inclose proximity thereto and having one end bent inward to engage thegroove and the other end extending outward with respect to the bolt, itsextremity being bent rearward to engage or overlie one of the outerfaces of the nut.

In testimony whereof, we afilx our signatures to this specification inthe presence of two subscribing witnesses.
